What else can I use the TX for if I get this heli? If the TX can be used for something else I might consider the investment!
Thought about the Solo 100 but this looks nicer! Since the SP100 is only cheap in the US (much more expensive elsewhere) this costs less for me than the SP100.

Well, 4 to 5 minutes worth of CP helicopter time, I'd say it's not too bad. It'll be an intense 4 to 5 minutes, depending on the pilot's skill and the tricks he'd be pulling off. Whoever thinks flying this for 4 minutes is just as intense as flying a V911 / 9958 for 4 minutes, should really think again.
